This question has been discussed by many people in the wake of recent suspension of a Wheaton professor. Here are two great biblical responses I’ve found. First, from Rev. Al Mohler and the second, from apologist Dr. James White.
The significance of this question is that “Hard times come with hard questions, and our cultural context exerts enormous pressure on Christians to affirm common ground at the expense of theological differences. But the cost of getting this question wrong is the loss of the Gospel,” according to Mohler.
A statement made by a professor at a leading evangelical college has become a flashpoint in a controversy that really matters. In explaining why she intended to wear a traditional Muslim hijab over the holiday season in order to symbolize solidarity with her Muslim neighbors, the professor asserted that Christians and Muslims worship the same God.
Is this true?
The answer to that question depends upon a distinctly Christian and clearly biblical answer to yet another question: Can anyone truly worship the Father while rejecting the Son?
The Christian’s answer to that question must follow the example of Christ. Jesus himself settled the question when he responded to Jewish leaders who confronted him after he had said “I am the light of the world.” When they denied him, Jesus said, “If you knew me, you would know my Father also” (John 8:19). Later in that same chapter, Jesus used some of the strongest language of his earthly ministry in stating clearly that to deny him is to deny the Father.
Christians and Muslims do not worship the same God. Christians worship the triune God, Father, Son, and Holy Spirit, and no other god. We know the Father through the Son, and it is solely through Christ’s atonement for sin that salvation has come. Salvation comes to those who confess with their lips that Jesus Christ is Lord and believe in their hearts that God has raised him from the dead (Romans 10:9). The New Testament leaves no margin for misunderstanding. To deny the Son is to deny the Father.
He does not stop there and I recommend reading his entire response.
Dr. James White is an apologist who debates with people around the world, including Muslims. So his Facebook note on the subject is also an excellent resource for this question.
White quotes from the Qur’an and its rejection of a triune God and other points central to biblical Christianity (nature of God, the nature of Christ). His post is well worth reading and I expect he’ll have a more detailed discussion about this on the Dividing Line soon, if he hasn’t already.
